WOVEN-WIRE CLAMP.

Specification of Letters Patent.

Patented Apr. 28, 1914.

Application filed May 5, 1913. Serial No. 765,513.

Be it known that I, G. BURNS Pensons, a citizen of the United States, residing at Darfur, in the county of Tatonwan and State of Minnesota, have invented certain new and useful Improvements in Toven- Tire Clamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it aj pertains to make and use the same.

My invention has for its object to provide an improved clamp especially adapted for use in conjunction with wire stretchers in putting up woven wire fences.

To the above end, generally stated, the invention consists of the novel devices and combinations of devices hereinafter' described and defined in the claims. f

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Referring to the drawings: Figure 1 is a view in side elevation, showing the improved clamp secured to the pulling cables of a pair of wire stretchers and applied to a woven wire fence; Fig. 2 is an edgepelevation of one end of the improved clamp; and Fig. 3 is a view in transverse section, taken on the line m3 w3 of Fig. 1.

The numerals 1 and 2 indicate a pair of clamping bars. To the inner face of the clamping bar 1 is secured a. gripping bar 3, as shown, preferably angle-shaped in cross section, with its flanges secured to and set part way into said clamping bars. Seated and rigidly secured in shallow grooves 4, formed in the inner face of the clamping bar 2, is apair of vertically extended gripping bars 5 that are, as shown,K

preferably rectangular in cross section. The gripping bars 3 and 5 extend the full length of the clamping bars l and 2, and the bars 5 are laterally spaced apart to permit the verteX of the bar 3, which is located attbe intermediate portion of the clamping bar 1, to project between the bars 5, when the clamping bars 1 and 2 are pressed together. Obviously, these gripping bars 8 and 5 form three point contacts that extend the full length of the clamping bars 1 and 2, and kink or bend the longitudinal wires of a woven wire fence a.

The clamping bars l and 2 are secured to the outer ends of the pulling cables b of a pair of wire stretchers, notl shown, by means of grapple hooks c, that embrace the longitudinal outer edges of the clamping bars 1 and 2. For the purpose of this case, it is not thought necessary to show the wire stretchers, as they form no part of the present invention.

A pair of clamps, each comprising an inner and an outer yoke 6 and 7 respectively, is provided for pressing the bars 1 and 2 together. These clamps are located one at each end of the clamping bars 1 and 2 but, in case the bars 1 and 2 are extremely long, an intermediate clamp may be used. The inner yokes 6 embrace the clamping bar l, and the free ends of their prongs are bent laterally inward to afford retaining lugs S, that are slidably mounted in grooves 9 formed at the inner longitudinalV edges of the clamping bar 1. The prongs of the inner-'yokes 6 are provided, at their longitudinal edges, with outwardly extended flanges 10, which embrace and hold the prongs of the outer yokes '7 for straight line endwise sliding movement. The outer yokes 7 embrace the two clamping bars 1 and 2, and the free ends of their prongs are bent laterally inward to afford retaining lugs 11 that slidablyengage the outer longitudinal edge portions of the clamping bar 2.

To permit the clamping bar 2 to be rcmoved laterally from the clamping bar 1 and out of engagement with the outer yokes 7, one prong of each of said yokes 7 is provided with a hinge joint 12, which permits the retaining lug 11 of said prong to swing into and out of locking engagement with the clamping bar 2. A set screw 13 is provided for each outer yoke 7 and has screw threaded engagement with the transverse portion thereof. The inner ends of said screws impinge against the transverse portions of the clamping yokes 6. The outer yoke 7 is held for limited endwise sliding movement, with respect to the inner yoke 6, by means of a screw stud 14 and a set screw 15. The intermediate portions of these screws 14 and 15 project through longitudiot.' the same by the pulling cables Z). Bv

`one of said hars. an outer clamping yoke embracing said bars, the prongs of said longitudinal adjustments on the clamping bars l and 2.

From the above description, it is evident that all or' the longitudinal wires of the Jfence a are securely held by the improved clamp, thereb)7 preventing the fence from pulling out of shape during the stretching applying a pullingcable to each end of the improved clamp, different tensions may be placed thereon, to keep the vertical wires of the fence in their proper positions. .n securing the improved clamp to a woven wire fence, the yokes 6 are rst secured in proper vertical adjustment on the clamping bar l, by the set screws l5. The clamping bar 2 is then placed in position within the yokes 7, and the two bars l and 2 are drawn together by means ot' the set screws 13. lilhilethe clamping bars l and 2 are being secured together, the gripping bar 3 bends or kinks the engaged portion oli' the fence a between the gripping bars .3, thereby securing the same against slipping.

The above described device, while extremely simple and of comparatively small cost to mamrtacture, is thought to be highly etlicient tor the purpose had in view.

lVhat l Vclaim is:

l. A device ot' the kind described, comprising a pair of cooperating clamping bars having', on their opposing faces, gripping bars, an inner clamping Vyoke mounted on having', on its prongs, retaining lugs and outer yoke being mounted for endwise sliding movement, with respect to said inner yol'ie, and an adjusting device between said two yokes, inr combination with a pulling device applied to said bars.

A device ot the kind described7 comprising a pair of cooperating clamping bars having, on their opposing faces, gripping bars, an inner clamping yoke mounted on one oi' said bars, an outer clamping yoke having, on its prongs, retaining lugs and embracing said bars, the prongs of said outer yoke being mounted tor endwise slidl Copies of this patent may be obtained for five cents each,

ing movement, with respect to said inner yoke. and an adjusting device between .said two yokes, one olf the prongs ot said outer yoke having a hinged section, in combination with a` pulling device applied to said bars.

2). A. device ot the kind described, comprising a` pair ot cooperating clamping bars having, on their opposing` faces, gripping bars arranged for three point contact with the wires ot a `tence, an inner clamping yoke mounted on one of said bars, for longitudinal adjustments thereon` means for securing said inner yoke in different longitudinal adjust-ments. an outer yoke liaving, on its prongs, retaining lugs and eml facing said two bars, the prongs ot said outer yoke being mounted ttor endwise sliding movement, with respect to the inner yoke, and an adjustingl device between said two yokes, in combination with a pulling device applied to the said bars.

l. A device of the kind described, comprising a pair ot coi'iperating clamping bars having, on their opposing faces, gripping bars arranged for three point contact with the wires ot a tence, an inner clamping yoke mounted on one otl said bars, ior longitudinal adjustment thereon and having, on its prongs, retaining lugs. means Jfor securing said inner yoke in ditterent longitmlinal adjust1nents,an outer yoke having. on its prongs, retaining lugs and embracing `said two bars` the prongs of said outer yoke bcing mounted, tor endwise sliding movement, on the inner yoke` an adjusting device between said two yokes. and means l'or limiting the endwise sliding movenient ot said outer yoke with respect to said inner' yoke, one of the prongs ot said outer yoke hav ing a hinged section. in combination with a puiling devicey applied to the said bars.

in testimony whereof l aliix my signature in presence ot two witnesses.
